Clean the lint screen every timeyou use the dryer. A clogged lint screen can make your dryer work harder - and it can be a fire hazard. Also, check your dryer vent and hose periodically to prevent buildup. This can also cause your dryer to use more energy and be a fire hazard.

Use a clothesline or clothes rack to dry clothes whenever possible.

Dry one load of clothes immediately after another to take advantage of a pre-heated dryer.

Buying New Appliances

It pays to invest in energy efficiency. In some cases, the money you save in energy costs can pay back the purchase price in just a few years.

Choose the capacity (especially with a heating and cooling system) that's right for your home and family. A system that’s too big wastes energy and costs you more money. A system that is too small can run more often and become overworked.

Replace inefficient appliances, even if they're still working. A refrigerator from 2001 uses 40% more energy than a new, ENERGY STAR model.

Shop for heating and cooling systems during the off-season. Many heating and cooling manufacturers offer significant rebates and promotions during seasonal sales. Plus, dealers may charge less for installation.

Shop for appliances when prices are discounted. Appliance sales are often offered around holidays like July 4, Memorial Day, Labor Day and Christmas.

Investigate new technology carefully. Some innovations, like convection ovens or argon-filled windows can lower your energy costs and make life more convenient. Others, such as commercial-grade kitchen appliances, might be merely expensive cosmetic enhancements.
